Many organizations provide a version control system for tracking software code changes. Engineers, programmers, and software coders check code into the version control system as changes are made. Some changes function as intended and some do not. Changes that do not function as intended include coding errors that are detectable using regression tests and coding errors that are undetectable with existing regression tests. In either case, coding errors can cause productivity loss. In the undetectable case, a coding error also carries the risk of causing customer data loss, loss of revenue, and/or a damaged reputation.
